[gentoo-user] No kernel boot after inserting more ram

[gentoo-user] No kernel boot after inserting more ram

[José Pedro Saraiva]

[-- Attachment #1: Type: text/plain, Size: 614 bytes --]

Hi all, wise gentoo users!
I've recently bought an extra GB of RAM for my laptop. After inserting it,
kernel refuses to boot, it hangs at "Booting the kernel"
I'm sure there's nothing wrong with the RAM, so it must be some other issue,
perhaps related with my boot options?
Any help or ideas are welcome :)

Here's an extract of my grub.conf:

title  Gentoo 2.6.22-r8
root (hd0,1)
kernel /boot/kernel-2.6.22-r8 root=/dev/sda5
splash=verbose,fadein,theme:emergence fbcon=scrollback:128K
console=/dev/tty1 combined_mode=libata
initrd /boot/fbsplash-emergence-1024x768



Best regards,
José Pedro

Well, if you haven't changed anything else other than the RAM module since the 
last time you booted the machine, then the problem would not be with your 
Grub configuration . . .  If you have, then revert the change.

Boot a LiveCD and run memtest86.  Sometimes even new memory modules are duff.

The first thing is to re-insert the RAM very carefully,
then to check that no other connections got dislodged accidentally.
Just my bit of Gentoo wisdom (smile).

Just a thought... Did you enable High Memory support in your kernel?

Processor type and features  --->
 High Memory Support  --->
  (X) 4GB

Nothing to do about it...
If he's using amd64 that option doesn't even exist.
And even if he's on x86, if that option is not enabled, it will boot, but
will just not use all the memory phisically available.

I don't know if you've tried this one already but another idea would be
to enter the system setup (BIOS) and just save the changes, then reboot.
You used to have to do this after any physical changes with RAM, though
I haven't seen it in years.

Just something else to try.

How? Have you run memtest?

An alternative to running memtest (which is quite easy to do, I might
add) would be to remove the original RAM and see if the computer boots
with the new RAM only.

Alternatively, you could just run memtest, as it is included with many
BIOSs now. It doesn't take long to identify problems, if there are any.
I find that test #5 is the best test for finding problems, however it
tends to keep you in the dark until it's finished the test.

Following your replies I've done the following, in an attempt to isolate the
problem:
(memory #1 - "old" memory, memory #2 - new memory)

- Runned memtest on both memories with 0 errors
- Booted with both memories... kernel hang
- Booted with memory #1 on slot #1 successfully
- Booted with memory #1 on slot #2 successfully
- Booted with memory #2 on slot #1 successfully
- Booted with memory #2 on slot #2 successfully
- Booted with both memories on windows successfully

For some reason, my kernel hangs if I have 2 GB of RAM installed.
And I do have High memory support (4GB), although that doesn't seem
relevant.
Ideas? :X

Thank you all for the quick replies.
Cheers

Well, after all kinds of tests and trying different types of memory
configurations, I can only conclude that my kernel boots normally with 1 GB
of RAM installed but hangs when I have 2 GB of RAM installed. I can't find a
logical reason for this to happen.

Any pointers or suggestions are welcome,

Hi,

I guess your kernel is configured to support only 1GB of RAM. In the
kernel configuration look for "Processor Type and Features"
There you find the Option. High Memory Support.
Probably it is set to "off". Set it to 4GB then recompile the kernel.
That should do it.

have fun
Tom

This is surprising.

Have you tried to boot from a liveCD with both memory modules inserted?

That was already suggested in a previous reply :)
I do have High Memory Support enabled with 4GB, still, it refuses to boot!
